Esx_policejob call extras

i cant find any information , when i want to have “extras” on the vehicle the must spawn

{ model = ‘polmav’, label = ‘Police Maverick’, livery = 0, price = 1 }
I can call a Livery but no extras?

The vehicle model must also have extras in the vehicle file. If not it won’t have any!

so i cant call extras over the garage , i must Edit it in meta?

No, you must also add the models for the extras. Else it will still not add any new modifications!
